' SPIRAL FOUNTAIN BRUSH.

Application filed May 3,

To all whom it may concern:

Be it known that I, MILTON JAcoBs. a citizen of the United States,residing at Poplar Bluff. in the county of Butler and State of Missouri,have invented certain new and useful Improvements in Spiral FountainBrushes, of'whi'ch the following is a specificat-ion, reference beinghad to the accompanying drawings; 1

This invention relates to fountain brushes, and has for its object toprovide a fountain brush adapted to enter a small passage.

Another object is to provide a fountain brush capable of being rotatedor oscillated in a small passage to clean all portions of the passage.

It is also an object of the invention to provide a fountain brush ofthis character including a liquid conduit, around which a brush isdisposed, portions of the conduit being exposed and provided withopenings, to permit the discharge of liquid therefrom.

It is a further object of the invention to provide a fountain brushhaving a discharge conduit, the conduit having a series of openings, anda spiral brush detachably connected at its ends to the conduit, thebrush being positioned to receive liquid discharged from the conduit.

With these and other objects in view, the invention consists in theimproved construction and arrangement of parts to be hereinafter moreparticularly described, fully claimed, and illustrated in theaccompanying drawings, in which Figure 1 is a view in elevation of afountain brush constructed in accordance with an embodiment of theinvention;

Figure 2 is a longitudinal sectional View of the conduit of the brush;

Figure 3 is a perspective view of the core of the brush;

Figure 4 is a transverse sectional view of the structure shown in Figure3; and

Figure 5 is a section taken on the line 5-5 of Figure 2.

Referring to the drawings, 5 designates the main supporting means orbody member of the fountain brush, said means consisting of-a sheet ofmaterial which is coiled upon itself to provide a conical conduit, theedges of the sheet being secured to each other by any suitable means.The conduit is provided with a series of longitudinally extending outletopenings 6 which register with similar outlet openings provided in the1922. Serial No. 558,262.

oppositeportions of the conduit. The apex portion 7 of the conduit 5 isclosed by a plug 8 which :is;firmly secured to the apex portion, theplug having a shoulder 9 adapted to engage the apex of the conduit.The-pro- .jecting portion 10 of the plug is threaded, the purpose ofwhich will be hereinafter described.

The opposite end portion 11 of the conduit is threaded, while projectinginwardly of the threaded portion and outwardly of the conduit is athreaded lug 12. The threaded end portion 11 of the conduit is intendedfor connection to a coupling 13, a pipe section 14 being connected tothe coupling. The opposite end pipe section 14: is provided with a valve15, while projecting from the valve is a coupling 16 adapted to beconnected to a hose or like conduit, so as to permit movement of thedevice in the desired manner, the pipe section 14 serving as a handlefor the brush, while the valve 15 can be used to control the supply ofliquid passing through the brush.

In connection with the conduit 5, a brush 17 is used, said brush beingof the twisted wire type, having a flexible wire core 18 through whichthe bristles of the brush extend. An eye 19 is formed at one end of thewire, while an eye 20 is formed at the opposite end of the wire. Thebrush is constructed in spiral formation, so as to encircle the conduit5 longitudinally thereof, to provide a brushing surface at all portionsof the conduit. The eye 19 which is disposed at the smallest end of thebrush is adapted to receive the threaded portion 10 of the plug 8, a.thumb nut 21 being used to hold the eye in engagement with the plug.

The eye 20 is adapted to receive the threaded I lug 12, a thumb nut 22being used to prevent disengagement of the eye from the lug. It willthus be noted that the brush is connected to the conduit in such amanner that the connecting means does not obstruct the passage of liquidtherethrough or interfere with the operation of the brush.

In view of the longitudinally tapered formation of the brush 17 and thefact that it is spiral, permits the same to enter a small passage, suchas a tubing, to thoroughly clean the same. that only one opening of eachpair of registering openings of the conduit is covered by the brush, theopposite opening being unobstructed. so that portions of the liquid Itwill also be noted brushes of various sizes may be used with the sameconduit, as all that is necessary to remove the brush is to unfasten thethumb screws 21 and 22 and withdraw the conduit from the center of thebrush.

From the foregoing it will be readily seen that this invention providesa novel form of fountain brush which in View of its spiral brush andcompact form is unlimited in its utility. mits the conduit to receiveany kind of liquid, and notwithstanding these features, the device issimple in construction.

What is claimed is A fountain brush comprising a conical Furthermore,its construction perconduit constituting a nozzle and having a threadedstem extending axially from its apex, a clamping nut for said stem, thenozzle being provided with a plurality of rows of perforations, thelarge end of the nozzle being provided with a threaded stud andcooperating nut. the outer face of the tapering nozzle being smooth, anarrow flexible brush clampingly engaged at one end to the large end ofthe nozzle by means of the nut and stud, and extending spirally aroundthe nozzle and having its other end clampingly engaged with the stem atthe apex of the nozzle by means of the nut thereon, the brushoverlyingcertain of the openmgs.

In testimony whereof I hereunto aflix my signature.

MILTON JACOBS.
